But there are still more tiles; and it is not good to just pile them up.Aber ich habe noch mehr Fliesen und es ist nicht gut, sie einfach aufeinander zu stapeln.Pero tengo más losetas y no sirve a solamente apilarlas.

Interesting, all of these really old ones (XIX th century) are encaustic ceramic tiles. I also saw some cement tiles, but not so beautiful patterns and therefore much newer. I must assume, that the invention of cement tiles started somewhere in the south of France.
